of roller-bearin gs interposed between the axle and the rim of thewheel.

It provides, further, other novel features of construction hereinafterfully described and claimed.

In the accompanying drawings, which illustrate my invention, Figure 1 isa vertical sectional View taken on the dotted line a b of Fig. 4, someparts being shown in elevation and portions being broken away. Fig. 2 isa 1onmounted on the axle, which is shown in elevation. Fig. 3 is atransverse vertical sectional view taken on the dotted line 0 d of Fig.4, the wheel-rim being shown in elevation and not in section. Fig. at isa horizontal sectional view taken on the dotted line cf of Fig. 3, theencircling ring, rollers with the enlarged circular heads, cones, andthe spacing-ring being shown entire. Fig. 5 is an end view of the wheel,the axle being shown in vertical cross-section. Fig. 6 is an endelevation view of the spacing-rollers and encircling ring, the rollerswith the circular heads being shown in cross-section. Fig. 7 is an endview of the spacing-ring and the circular heads of the rollers, theaxial projections thereon being represented in crosssection.

Similar numerals of reference indicate similar parts.

1 indicates the axle, provided with the two octagonal portions 2 and 3.Fitted on the said octagonal portions 2 and 3 are two cones 4 and 5,respectively, provided with externallyscrew-threaded sleeve projections,on which are fitted, respectively, the cones 6 and 7, provided each withan octagonal end having radially-disposed screw-threaded holes 8, in

Serial No. 726,661. (No model.)

which may be placed set-screws for securing the cone to the axle.Arranged around the cones 4, 5, 6, and 7, respectively, and bearingthereon are a series of dumb-bell-shaped rollers 9, provided withcircular heads 10, which are the portions of the rollers which bear uponthe cones. For keeping the rollers 9 at suitable distances apart I haveprovided a series of spacing-rollers 11, disposed alternately betweenthe rollers 9 and having a tongue-andgroove ,connection therewith toprevent lateral movement of the spacing-rollers relative to the mainrollers 9. This tongue-and-groove connection is provided, preferably, byproviding in the middle of each roller 9 an annular flange 12, whichfits into an annular recess or depression 13, provided in each of therollers 11. A ring 14, provided on its inner wall with an annular flange15, embraces the spacingrollers 11, the flange 15 fitting the peripheralrecesses 13 of the spacing-rollers. An additional spacing mechanism isprovided, comprising a ring 16, provided on its inner wall with recesses17, which fit, respectively, the peripherally-grooved axialprojections18, extending one each from one end from each roller 9.

19 indicates the wheel-rim, to which the wheel-hub is secured. Thewheel-hub comprises the end plates 20 21 and 22 23, secured,respectively, to the inner and outer ends of the wheel-rim, thering-plates 21 and 23 being secured to the wheel-rim directly and thering-plates 20 and 22 being secured, respectively, to the outsides ofthe plates 21 and 23. Each of the ring-plates of the hub is providedwith an inner annular seat, in which run the circular heads of therollers 9. To prevent ingress of dust into the roller-bearings of thewheel, dust-guards are provided, comprising the inwardly extendingringplates 24c and 25, secured, respectively, to the hub-plates 20 and22 and provided each at its inner edge with a curved annular recessoverlapping an outwardly-extending flange on the periphery of a ringsecured to the adjacent cone. These cone-rings are secured,respectively, as follows: the ring 26 to the cone 6 and the ring 27 tothe cone 7. -The octagonal portion 2 is of the same size or smaller thanthe similarly-shaped portion 3 of the axle, so that the cones 5 and 7may be slipped off and on the axle. Lateral movement of the cones on theaxle for the purpose of adjustment may be accomplished after looseningthe set-screws (not shown) which hold the cones on the axle.

In operation the rollers 9 run around the cones 4, 5, 6, and 7, theadjustment of which is obtained by properly rotating, the cones 6 and 7on the threaded portions of the cones 4t and 5, respectively. Therollers 9 are kept separate from each other by means of thespacing-rollers 11 and the spacing-ring 16.

My invention is adapted to use on various kinds of vehicles, such ascarriages, wagons, cars, 850.

Various modifications may be resorted to while remaining within thescope of my invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patcut, is-..-.-.
